Definitions

  • the present invention relates to an intraocular lens cartridge for insertion into an injector for injecting an intraocular lens (IOL) contained within the cartridge into an eye of a patient.
  • IOL intraocular lens
  • One of the operative treatments used to treat cataract is a method of removing a natural crystalline lens from an eye of a patient and then injecting an intraocular lens (IOL) in place of the natural crystalline lens.
  • IOL intraocular lens
  • first generation IOLs were manufactured from rigid PMMA and were implanted into the eye using forceps through large (5-6 mm) incisions.
  • the large incision size increased the risk of infection and could lead to induced changes in the shape of the cornea and also potentially cause astigmatism of the eye after the operation.
  • a next generation of foldable IOLs was developed that could be introduced into the eye through a reduced incision size (2-4 mm) using an injector.
  • IOLs typically comprise a lens portion and a pair of resilient haptics extending outwardly from opposite sides of the periphery of the lens portion.
  • the haptics aid in locating the IOL in a correct position in the eye and in maintaining the IOL in that correct position.
  • the following steps are usually performed: first making an incision in the eye; fragmenting and aspirating a clouded natural crystalline lens through the incision; and then injecting the IOL into the eye through the incision to implant it in place of the natural crystalline lens.
  • a first generation of injectors typically consisted of reusable titanium bodies fitted with disposable plastic cartridges, those cartridges being loaded with a foldable IOL at the point of use.
  • injectors 10 were plastic, disposable, single-use injectors. These often had cartridges 20 that were integral with the injector bodies 12, the IOL 50 being inserted at the point of use as in the previous injectors mentioned above. It is also known for the cartridge 20 to be a separate element, removably fitted into a loading bay of the injector 10.
  • the foldable IOL 50 in the cartridge 20 is positioned so as to be aligned with a bore 14 in the injector 10 containing a plunger 16. A relatively narrow end portion 16' of the plunger engages the IOL 50 to urge the IOL toward the tip 18 of the injector.
  • the IOL 50 is held within the injector 10 and engaged by the plunger 16 in an unfolded state, in which case the tip 18 of the injector 10 will be tapered so as to fold the IOL into a smaller shape as it is pushed toward and through the tip 18 by the plunger 16.
  • the IOL 50 is folded just prior to insertion by manipulation of the cartridge 20 and is engaged by the plunger 16 in a folded condition, as described below. The folded IOL 50 is pushed out of the tip 18 of the injector 10 inserted in the eye through the incision and is spread (unfolded) and placed in the eye.
  • IOLs 50 It is essential for IOLs 50 to be stored unstressed so as not to become permanently deformed over time. Accordingly, IOLs 50 are not held in a folded condition over a long period of time (i.e. in storage).
  • Preloaded injectors designed for delivery of hydrophobic IOLs usually incorporate lens storage within the main injector body. Due to its simplicity, this is a more preferable option for a preloaded injector and is possible because hydrophobic IOLs can be stored in a non-hydrated or 'dry' state.
  • Examples of known preloaded systems include four fully preloaded injectors: Isert Acrylat, hydrophobic aspheric; Acrysert Acrylat, hydrophobic aspheric; NX-1 Nex-load Acrylat, hydrophobic aspheric; and KS3-Ai Silicone aspheric (respectively manufactured by Hoya, Alcon, Domilens and STAAR-Domilens).
  • hydrophilic IOLs In contrast to hydrophobic IOLs, hydrophilic IOLs must be stored hydrated, normally completely submerged in a saline solution. As a consequence, semi-preloaded injectors for hydrophilic IOLs, requiring insertion of a cartridge into the injector by the end user, are used for hydrophilic IOLs. The IOL is held within a cartridge submerged in saline during storage, then removed and attached to the main body of an injector (dry) immediately prior to use, much as described above in connection with the early titanium injectors 10.
  • Examples of known semi-preloaded injectors include: Polysert PPS Acrylat, hydrophobic aspheric; XL Stabi Sky Acrylat, Hydrophilic, aspheric; and Slimflex m1.2.3, Acrylat hydrophilic, aspheric (respectively manufactured by Polytech, Zeiss and Technoko).
  • the IOL 50 may be held in an unfolded state within the injector 10. Accordingly, when the cartridge 20 is inserted into the injector 10, the IOL remains unfolded. It is only once the IOL is engaged and urged out of the tip 18 of the injector by the plunger 16 that the IOL becomes folded for injection through the incision in the eye.
  • the cartridge is manipulated prior to insertion into the injector in order to fold the IOL within.
  • the currently most common IOL injector cartridge format includes a pair of hinged flaps that, in a first configuration, define a chamber that holds the IOL in an unfolded state. When the flaps are hinged together, the chamber becomes reduced in size, thus folding the IOL within.
  • the IOL is inserted into a loading bay of the injector (defined within the integral cartridge) at the point of use in an unfolded state and the flaps of the cartridge are then closed to fold the IOL.
  • a cartridge according to the preamble of claim 1 is known from document WO-A-03/04525 , according to the preamble of claim 6 from WO-A-2004/092780 .
  • the first portion comprises at least one plate and at least one adjacent land
  • the second portion comprises a land corresponding to the or each of the at least one plates of the first portion and a plate corresponding to the or each of the at least one lands of the first portion.
  • the plates of the first and second portions are interdigitated and interior surfaces thereof define, at least in part, the storage chamber, whereas in the implanting configuration the plates of the first and second portions overlie their respective corresponding lands.
  • At least one of the plates may include a tooth at a distal end, the corresponding land including a detent, the tooth engaging the detent when the first and second portions are in the implanting configuration.
  • the first and second portions are interengaged by a hinge, pivotably moveable relative to one another about the hinge.
  • the first and second portions may each comprise an arcuate segment of the inner surface that, in the implanting configuration, respectively define opposite halves of the smooth-bored chamber; the first portion comprising first and second spaced plates projecting from an upper side of the arcuate segment; and the second portion comprising a third plate projecting centrally from an upper side of the arcuate segment; the third plate of the second portion being disposed between the first and second plates of the first portion.
  • the first and second portions of the cartridge according to the first aspect may each comprise a flap extending in a radial direction along a line from the hinge.
  • the flaps of the first and second portions may be aligned with one another when the first and second portions are in the implanting configuration.
  • first and second portions are slidably moveable relative to one another.
  • the first portion and the second portion may be substantially identical, the first portion being rotated 180° relative to the second portion about both a vertical and a horizontal axis.
  • the first and second portions may each comprise:
  • the smooth-bored chamber of the implanting configuration is cylindrical.
  • the smooth-bored chamber of the implanting configuration is tapered in the longitudinal direction.
  • the cartridge further includes a foldable, implantable medical device.
  • the medical device is an intraocular lens.
  • a medical device injector comprising:
  • a method of loading a medical device injector comprising:
  • comprising encompasses “including” as well as “consisting” e.g . a device “comprising” X may consist exclusively of X or may include something additional e.g . X + Y.
  • top, bottom, sides and other terms describing the orientation of features are not intended to be limiting and are purely included in order to facilitate the description of the relative location of those features in the context of the accompanying drawings. In use, the features may be disposed in other orientations.

  • the step of moving the cartridge 120, 220 from the storage configuration into the implanting configuration could take place prior to the removing step, the IOL 50 thus being folded whilst still in the packaging.
  • the cartridge 120, 220 fully encloses the IOL at all stages of storage and implantation, right up to the point when the IOL is expelled from the injector into the eye. This therefore greatly reduces the risks of contamination and/or placement errors.
  • the cartridge 120, 220 and associated injector have been described in the context of the storage and injection of intraocular lenses 50, and especially hydrophilic IOLs, the skilled person would appreciate that the invention has further application and may equally be applied to the storage and implantation of non-hydrophilic IOLs (which can be stored dry for up to five years) or other foldable medical devices, with suitable adaptation, where necessary, of the shape and configuration of the storage and implantation chambers 140, 140'; 240, 240' and of the injector.
  • the implanting chamber 140', 240' could be of any appropriate cross sectional shape, such as oval, square or octagonal. Moreover, it is not necessary for the sides of the bore to be parallel. Instead, the bore could be tapered, narrowing in the longitudinal direction. Also, the cross sectional shape of the bore could change along its length.
  • the cartridge 120, 220 could be made of multiple materials so as to achieve optimum properties and/or cost.
  • the interior surfaces 131, 135; 231, 235 defining the bore of the implanting chamber 140', 240' could be made of a highly lubricious material whilst the rest of the cartridge is made of standard grade plastics.
  • the plates 128a-c; 228a-f could be made of a material that has particularly good properties for resilience, for example.
  • the entire cartridge 120, 220 could be coated in a lubricious coating or could contain a lubricious agent to reduce friction thereby facilitating ejection of the IOL 50 from the cartridge 120, 220.
  • the injector may contain a lubricious sleeve (not shown) to be pushed over the folded IOL 50' by the injector plunger after the cartridge has been inserted into the loading bay of the injector.
  • the cartridge could be incorporated into and be integral with the injector.
  • the cartridge may have an integral nozzle section, for use with an injector having no nozzle or tip section.
  • the cartridge of either aspect of the invention may have either more or fewer plates and corresponding lands.
  • first flap 150 is described as having first and second arms 150a, 150b connected by a shoulder 151, it will be appreciated that the shoulder 151 could be omitted. In fact, just a single arm 150a could be used in conjunction with the second flap 154. If no flaps were provided, the user would still be able to move the first and second portions 122, 124 together to the implanting configuration, but with greater effort.
  • the first and second portions 222, 224 of the cartridge of the second aspect of the invention do not have to be identical, although this facilitates manufacture.
